Answer:

$-\frac{5}{2}, -2, 1.7$

Step-by-step explanation:

1. Make fraction to decimal

$-\frac{5}{2} = -2.5$

2. Order from least to greatest.

1.7 > -2 > -2.5

Least to greatest : $-\frac{5}{2}, -2, 1.7$

Answer:

$(B)r=\dfrac{85}{12}$

Step-by-step explanation:

Given a circle centre J

Let the radius of the circle =r

LK is tangent to circle J at point K

From the diagram attached

LX=6
Radius, XJ=JK=r
LK=11

Theorem: The angle between a tangent and a radius is 90 degrees.

By the theorem above, Triangle JLK forms a right triangle with LJ as the hypotenuse.

Using Pythagoras Theorem:

$(6+r)^2=r^2+11^2\\(6+r)(6+r)=r^2+121\\36+6r+6r+r^2=r^2+121\\12r=121-36\\12r=85\\r=\dfrac{85}{12}$

The length of the radius, $r=\dfrac{85}{12}$
